ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 301,684, dated July 8,:381"- Application tiled April 4, 1884. (No model.)

To @ZZ whom it may concern,.-

' Be it known that I, BURTON H. COOK, of Brooklyn, Kings county, SewYork, have invented certain new and useful Improvements in Ash-Sifters,of which the following is a specification.

f be dumped and by which they are discharged n from the side of the box.

One feature of my invention. lies in the special construction andarrangement of the chuteslide relativelytothe box and cylix1der,\vhereby it serves also as the lid to the box; and another feature consists-ina discharge-door on the side of the box operating in relation with theslide.

The remaining features of my invention lie in the special constructionof the hinges and catch of the removable lid-section of the cylinder,and also in certain minor details, as hereinafter fullyset forth andclaimed, whereby astrong,'simple, cheap, and effective ash-si fter isprovided. A Y

In the annexed drawings, Figure l is a sectional elevation of myimproved sitter, represented in the act of or prepared for sifting. Fig.2 is a similar view, represented in the act of dumping the siftedcinders. Fig. 3 is a fragmentary perspective view of the lid-section ofthe cylinder removed, showing the form of hinge and catch thereof. Fig.4 is a plan. view of the complete sifter. Fig. 5 is a perspective viewof the casting forming the socket-leaf of the hinge, and Fig. 6 isasection through both the socket and hooked leaves of the hinge shownengaged. Fig. 7 is a perspective view of the socket-plate of the catch;and FigS is a cross-section of the socket-plate, showing the;A barbofthe catch sprung therein.

Referring to Figs. l, 2, and 4, c1 indicates the base of the sifter,which is of the usual round and flanged form, adapted to fit on and overthe head of the aslrbarrel, as indicated in Figs. 1 and 2, and bindicates the casing of the sifter', which is preferably a squareupright box, rising centrally from the base a. In the upper part of thebox is inolosed the `cylindrical sieve A, which consists of a cylinder,c, of wire-cloth, xedto tworound wooden heads, d d, which heads arefitted with little metal trunnions e e, which are journaled in holesbored in each side of the box, thus forming an axis on which thecylinder is free to revolve withinthe box in the usual manner of rotarysifters, as will be readily understood from Figs. l, v2, and 4E. One ofthe trunnions is a little longer than the other, and is squared toreceive a crank, f, whereby the cylinder may be rapidly revolved to siftthe cinders in the usual manner. One section, q, of the'wirecloth c ofthe cylinder is removable to perniit theA insertion and removal of thematerial to be sifted, andl this lid-scction q is hooked or hinged atoneedge to the cylinder, and is provided with a catch to engage theopposite edge, whereby the lid may be easily removed or replaced whenrequired, yet is firmly held in place during the action of the sifter.The hinges and catch are of peculiar forni, wellshown in Figs. l, 3, Ll,5, and 6, to Which reference may be now had. The leaves h or parts ofthe hinge connected with the lid q are formed, as shown, with npturnedhooked ends h' and downwardly-turned stops z' i, the stops being adaptedto abut against the edge of the lid-opening in the Wire-cloth cylinder,While the hooks are adapted to hook into one of the meshes of the cloth,or preferably into a special socket-plate or leaf, k, (see Figs. 5, 6,and 4,) made of cast-iron, and riveted to the wire-cloth cylinder, asshown in Fig. 4. The socket-leaf, as shown best in Figs. 5 and 6, isformed with two openings, to ad mit the hook of the opposite leaf, theopenings being separated by a cross-piece or bridge with which the hookengages, as shown in Fig. 6. The cross-piece is strengthened by auupwardly-projecting dan ge, l1', and the edge of the socket isstrengthened by a downWardly-projecting flange, k2, against which thestop i of the hooked leaf abut-s, as shown in Fig. 6. The socket-leafla, and also the hooked leaf h, is cast with two rivet-holes, as shownin Figs. 5 and 6, to receive the rivets, whereby they are fastened to"IOO the wire-cloth cylinder, as shown in Fig. 4,' thus rendering theattachment secure. At the middle of the lid-section Q is riveted a loopof hoop-metal, forming a handle, n, whereby the lid may be easily movedinto or out of posiv ment with a mesh or socket in the opposite edge ofthe wire-cloth cylinder, as well shown in Fig. l, also in Figs. 3 and 4.have the barb of the catch-spring Z engage with a cast-ironvsocket-plate, m, (seeFigs. 4,

7, and8,) riveted onto the wire-cloth cylinder,

as shown in Fig. 4, this socket-plate being cast withtwo holes toreceive the rivets, and with an opening to receive the barb of thecatch, and also a downwardly-projecting lip or iiange, m', for strength,as well shown in Figs. 7 and 8. It will now be seen that the hinging andfastening devices of the lid are very strong, simple, and cheap, andeasily operated. Thus by pressing back the barbed loop of the catch Zthelid may be raised and swung upon the hooked hinges, which can be readilyunhooked from their socket-plates and the lid then placed aside, whilethe ashes and cinders are poured through the opening into the cylinder,after which the lid can' be again easily hooked in its sockets andclosed down, and-the catch sprung into its socket, which will hold thelid securely in place during the sifting operation, which is effected,as usual, by rapidly revolving the cyliuder by rotating the crank, whichwill cause the ashes to fly out through the meshes and fall into thebarrel below, while the cinders of useful size remain in the cylinder,as will be readily understood. It will be readily noted that the formand position of the catch is such that it has no tendency to loosenduring the revolution of the cylinder by centrifugal force or otherwise;but its tendency is rather to' tighten itself in its socket, thusrendering the position of ther lid secure. Then the cylinder is beingrevolved to sift the cinders, as above described, the box b is of coursecovered by the lid g, as shown in Fig. l, to pre-v vent the escape ofashes, and when the ashes have been sifted out the lid is removed, andthe cylinder is turned around to dump the cinders onto an inclined chuteor slide in- I Aserted across the box below the cylinder, by

which theV cinders may be discharged out through a side door and intothe scuttle placed beneath the same, as seen in Fig. 2. Now, accordingto my improvement it will be seen that the lid of the box, as seen inFig. 1, is also made to serve as the slide-chute, as seen in Fig. 2. Thelid g, as shown, is made considerably longer than necessary At0 coverthe top of the box, but of just the right Width to fit between the endwalls of the box,which, as seen in Figs. l and 2, project up above theside walls a distance equal to the thickness of I prefer to the cover,so that these walls embrace each side of the cover,while the cover restson the tops of the side walls, as shown. One end of the cover is formedwith a short rim-piece, g', projecting at right angles thereto, whichabuts against one side of the box when the cover is placed over thesame, as shown in Fig. l.V On one side of the box below the cylinder isformed a slit, o, extending the full width of the box, and within thebox, on cach side thereof, inclined ways o are formed, coincident withsaid slot, and inclining downwardly therefrom.a At the foot of theinclined ways, at the opposite side of the box, au opening is formed toprovide a dischargeorifice for the sifted cinders, which opening runsthe full width of the box, similar to the slot o, and is provided withan outwardlyopening hinged door, r, having a downwardlyinclinedinwardly-projecting iinger, s, thereon, as shown in Figs. l and 2, whichdoor normally gravitates shut, as shown in Fig. 1,' so as to prevent theescape of dust or ashes during the sifting, operation. The slot o isalso provided with an inwardly-opening valve or door, t, which normallygravitates againstl the side of the box, and thus closes the slot toprevent the escape of ashes. It will now be readily understood that whenthe sifting operation is nished the lid or cover g of the box is removedand inverted, and then slid into the slot o on the side of the box anddown the inclined ways 0, until the rim g IOO the edge of the base-rim ainto the scuttle or other vessel placed beneath the same to receivethem, as indicated in Fig. 2; hence by this means one part serves bothas the lid and the chute, thus rendering Vthe construction cheap andsimple and quite convenient in operation, as the mere removal andinsertion of the lid prepares the apparatus for dumping, andautomatically opens the valve t and door r, as shown in Fig. 2, whichmovement of the lid is very simple and is quickly effected. After thecinders are dumped, the slide is removed and placed on the top of thebox, as before, and the doors tr will of course close of their owngravity, thus preparing the box for the next operation of sifting. Itwill therefore be now readily appreciated that the several featuresdescribed combine to produce a very efficient sift-er of the rotaryclass,which at the same time is composed of few and simple parts, andthese of inexpensive durable construction and of easy operation.

Instead of forming the box with a flanged IIO I be made with a largereceptacle beneath to receive the ashes, if desired; but it is notthought desirc ble.

What I cla-ini is l. In a sitter, the combination of the sieve and itsinclosing-box open at the top, and having apertures on the sides belowthe sieve, with the movable slide g, adapted to fit above the sieve overthe top of the box, and form a cover therefor, and also adapted to tbelow the sieve across the box and form a chute to discharge thecinders, substantially as herein set forth.

2. The combination, with the sieve and its inclosing-box having adischarge-door on the side below the sieve and a slot at the oppositeside, of the slide g, adapted to enter the slot, extend across the box,and project through and open the said door, substantially as and for thepurpose set forth.

3. The combination, with the sieve and its inelosing-box having thesloto and the door r, with its inward projection s. of the slide g, adaptedlto enter the slotof thebox, project across the same, andconie in contactwith the projection s, and thus open the said door and keep it open, andthereby forni a chute by which the einders-are discharged.

4. The combination, with the sieve, of the' inclosingbox formed with theslot 0 on one side, the door r on the opposite side, and inclined Ways oextending across the' box, With `5. The combination, with the :sieve andsieve-box having two opposite sides higher Athan the sides at rightangles thereto, of the `lid g, formed with the ledge or rim g', adaptedto tit over the box between the higher sides, in combination with a wayacross the box below the sieve, and a discharge-door at the foot of thesame adapted to receive said lid, so as to form a dischargechute whenthe cinders are dumped, substantially as herein shown and described.

6. The combination, with the sieve-box, of the rotary sieve A, with itsmovable section g, having hooked hinge-leaves on one sideand asuitablecatch at the opposite side, with the corresponding sockets, 7c and m,substantially as herein set forth.'

7. The combination, with the sieve and sieve -boX having the slot o andvalve t, of a. movable chute-slide adapted to enter said slot, and adischarge-door on' the side opposite said slot, substantially as and forthe purpose set forth.
